ABOUT OIL SPILL
An oil spill is a release of a liquid petroleum hydrocarbon into
the environment due to human activity, and is a form of pollution. The
term often refers to marine oil spills, where oil is released into the
ocean or coastal waters. Oil spills include releases of crude oil from
tankers, offshore platforms, drilling rigs and wells, as well as spills
of refined petroleum products (such as gasoline, diesel) and their
by-products, and heavier fuels used by large ships such as bunker fuel,
or the spill of any oily white substance refuse or waste oil. Spills may
take months or even years to clean up.
Oil also enters the marine environment from natural oil seeps.Public attention and regulation has tended to focus most sharply on
seagoing oil tankers.
WHAT TO DO BEFORE
- Ttraining, inspection, and contingency plans for the avoidance, control, and shutdown of offshore operations.
- Using new Technologies which prevents oill spill.for example : Drilling blowout preventer - The primary safety control devices for well drilling . Blowout preventers contain a stack of independently-operated cutoff mechanisms, so there is redundancy in case of failure, and the ability to work in all normal circumstances with the drill pipe in or out of the wellbore.
WHAT TO DO AFTER
- Cleanup and recovery from an oil spill is difficult and depends upon many factors, including the type of oil spilled, the temperature of the water and the types of shorelines and beaches involved.
- Bioremediation : Use of Microorganisms or Biological agents to break down or remove oil.
- Controlled burning can effectively reduce the amount of oil in water, if done properly. But it can only be done in low wind and can cause air pollution.
- Solidifying: Solidifiers are composed of dry hydrophobicpolymers that both adsorb and absorb. They clean up oil spills by changing the physical state of spilled oil from liquid to a semi-solid or a rubber-like material that floats on water.
